 Mar18 awarded Popular Question Mar6 awarded Popular Question Oct13 awarded Yearling Oct10 asked Differential Equation Substitution Dec13 accepted Inductive Proof of Euler's Formula $v-e+r=2$ Dec7 awarded Nice Question Dec7 revised Probability of questions being on an exam Made the fractions d-fracs so that I could see them. Dec7 comment Probability of questions being on an exam Is it perhaps 1 minus that answer? (as $n$ decreases, the probability decreases.. Shouldn't it be the opposite?) Dec7 comment Probability of questions being on an exam I think something might be wrong. When I compute $\dfrac{\binom{60}{3}\binom{60-60}{7}}{\binom{60}{10}}$ I get 0.. Also, subbing in $n=30$ is giving me ~10%.

Maybe I'm confusing it with another one. I just thought I remembered it being answered as a pigeonhole principle question. I'll try to tackle it differently Dec6 asked Pigeonhole Principle on Graphs Dec6 asked Inductive Proof of Euler's Formula $v-e+r=2$ Dec6 answered Inductive Proof of Euler's Formula $v-e+r=2$ Dec6 accepted Bipartite Graph Counting.. Easy?
